Weeaemw -F. G. BEACH, OF HARTFRD, CONN^ECTICUT.

Letters .Patent No.184,986, dated December 15, 1868.

To 'all whom it ma/y concern Be it known that I, F. G. BEACH, of Hartford, in the county of Hartford, and in the State of Connecticut, have invented an Improved Ash-Sifter; and do hereby declare that the following is a full, clear, and

exact description thereof, reference being had to the accompanying drawing, making a part of this specification, iu which- Figure l is a topview with the cover removed.

Figure 2 is a veitical longitudinal section.

Letters of like'name and kind refer to like paits in each of the figures. Y

My invention relates to a class of devices known as ash-sitters, and used for separating partly-consumed coalfrom the ashes taken therewith from a stove -or furnace, without allowing the dust arising duringthe operation to escape; and

It consists in the means used for suspending a sieve within a suitably-enclosed reservoir, so that a reciprocating motion applied t'o the sieve shall cause analternate upheaving motion of each end, by which means' the coal and ashes are thrown to and from the centre of said sieve, and the ashes speedily and thoroughly separated from thecoal, and deposited in the bottom of the reservoir, without permitting any to escape in the form of dust.

In the annexed drawing- A represents a reservoir constructed of sheet-metal, much in the form of an ordinary clothes-boiler, with a cover, B, closely covering its top.

C represents a sieve, consisting of an oblong box of sheet-metal, open at its top, andl with a bottom, D

composed of perforated metal, wire cloth, or any suit.

able material used for such purpose. This bottom may be made adjustable, if desired, so as to permit it to be removed, and others, with diiferent-sized perforations or interstices, substituted.

Secured to each end of the sieve, near its bottom, is a piece of sheet-metal, c, curved outward and downward,-so as to form bearings for the lower ends of two loops or links of wire, E, suspended from suitable lugs or ears a attached to the inner ends of the reservoir A, near its top, as shown in the drawings.

The links do not hang vertically, but their Vlower ends are dlawn inward, so as to bling them at an angle of thirty degrees, or' thereabouts, from a perpen dicular line.

that, when moving in either direction, the forward end will be depressed and the rear end elevated,and that' it the sieve is swung quickly back and forth, its contents will be thrown alternately from each end towards the centre.

Motion is imparted to the sieve by means of a rod, v

F, which passes through an opening made by corresponding slits or notches in the ilange of the cover and top of the reservoir. The inner end of 'this rod is provided with a hook which passes through a hole near the top of the sieve, while upon its 'outer end is a wooden or other handle.

The operation of this device isso simple as to' be readily understood without further description. v

The advantages possessed by this invention over all others in use intended for a like purpose are, tiret, the peculiar motion imparted to the sieve is valmost iden-` tical with that given to the ordinary hand-sieve, and causes the coal and 'ashes to be more quickly and thoroughly separated than by any other means; second, lwhile performing the desired operation in' a more speedy and thorough manner, its parts are so few and simple that it can be furnished at as low a price as any now in market. Y

Having thus fully set forth the naturev and merits of my invention,

-VVVhat-I claim as new, and desire to secure by Letters Patent, is

' 1. suspending a sieve, C, within a suitably-enclosed reservoir, A, by means of the links E E, or their equivaient, so that a reciprocating motion -applied to said sieve shall cause an alternate .upheaving' motion of each of its ends, substantially asand for the purpose herein shown and described.

2. An ash-sitter, consisting of the reservoir A, cover B, sieve 0,' links E E, and rod F, when constructed in the manner and for the purpose substantially as herein` described.

In testimony that I claim the foregoing, I have hereunto set 'my hand and seal, this 22d day of October,

F. G. BEACH. [L. s.]- Witnesses:

THOMAS McManus', Ensim JOHNSON.
